RAILWAY-SLEEPER.

I lowing is a specification.

This invention relates to railroad-tracks, and includes a sleeper or sill made of cement, hardburned clay, or other plastic material, together with other improved means for supporting and maintaining in proper position the rails of the railway.

Inthe accompanying drawings, Figure 1 is a plan view of a section of track constructed according to this invention. Fig. 2 is an end or sectional view of the track. Fig. 3 is an erfiarged vertical cross-section of one of the s1 s.

Referring specifically to the drawings, the rails of the track are indicated at 6. The sleepers are made of clay or cement, as above indicated, and each consists of a block of suitgrooves 11 below the surface of the grourid,

being spread or flared outwardly below the grooves, as at 12, so as to prevent lift.

longitudinal rib 10 serves to prevent side slip, and the ribs 13, extending along the sill above. the groove at the surface of the ground, assist in holdingthe sill in place.

The sill has two longitudinal hollows or recesses in the body thereof, (indicated at 14,)

and these connect with bolt-holes, through which the bolts 15. extend to the top of the sill. The bolts may be inserted or removed through the holesl i. Said bolts hold the rail in place by means of the clips 16, which overlie the flanges of the base of therail.

The rails are prevented from spreading by tie-bars 17 of known construction, which are located and grip the bases of the opposite rails between the sills. These tie-bars may be of the usual construction, such as those used to connect switch-points.

The wooden plate 9 serves to cushion the shock of the rail and prevent fracture of the sleeper. A I

The sleeper gives a large. surface-bearing for the rail and on account of its shape is easy to keep in line. The sleepers are fireproof and can be molded at small cost. They may be applied to existing tracks by the substitution thereof for worn-out wooden ties.

What I claim as new, and desire to secure by Letters Patent, is-

-1. A sleeper for railroads, comprising a hol-.

low block of plastic material adapted to extend lengthwise under the rail and having a longitudinal recess in the top, in which. the rail rests, and ground-engaging ribs.

2. A sleeper comprising a hollow block hav ing a longitudinal depression in the top in which the rail rests and ground-engagingv ribs and grooves in the bottom and sides, and boltholes extending upwardly from the hollow through the top of the block.
